Question

Suggest some of the features of plants that will prevent insect and pest infestation.

Answer 1

Some of the features of plants that prevent insects and pest infestation are as follows:

(a) Hairy leaves are supposed to resist pest attacks, e.g. jassids do not attack cotton and leaf beetle does not attack wheat.

(b) The solid stem of wheat makes it resistant to stem sawflies.

(c) Nectar-less cotton varieties do not attract bollworms.

(d) High aspartic acid, low nitrogen and sugar content in maize lead to resistance to maize stem borers.
